Abstract

The main objective of this paper is to optimise energy harvesting design of piezoelectric and magnetic based on vibration excitation; an alternate method for predicting the power output of a bimorph cantilever beam using finite element method with harmonic analysis solver. Both power output generated from the electromagnetic and the piezoelectric were combined to form one unit of energy. In addition, the optimum model was analysed using parametric optimisation analysis solver in finite element analysis to produce an optimum power output. The result showed a maximum power output of 56.66 μW from 47.94 Hz, 4.905 m/s2, and 0.18 cm3 generated for resonance frequency with acceleration and volume. The decreasing size of the harvester with a low natural frequency produces a high-power output.

基于振动激励的混合能量收集的有限元优化

本文的主要目的是优化基于振动激励的压电和磁性能量收集设计;一种利用含谐波分析求解器的有限元法预测双晶型悬臂梁输出功率的替代方法。由电磁和压电产生的输出功率组合成一个能量单位。此外，利用有限元分析中的参数优化分析求解器对优化模型进行了分析，以获得最优的功率输出。结果表明，在47.94 Hz、4.905 m/s2、0.18 cm3的谐振频率下，随加速度和体积变化产生的最大输出功率为56.66 μW。具有低固有频率的收割机的减小尺寸产生高功率输出。
